Installation Continued installation for vertical termination Note: Vertical restrictor must be installed in all vertical installations. 1. Determine the route your vertical venting will take. If ceiling joists, roof rafters, or other framing will obstruct the venting system, consider an offset (see Figure 19) to avoid cutting load bearing members. Note: Pay special attention to these installation instructions for required clearances (air space) to combustibles when passing through ceilings, walls, roofs, enclosures, attic rafters, etc. Do not pack air spaces with insulation. Also note maximum vertical rise of the venting system and any maximum horizontal offset limitations. 2. Set the fireplace in desired location. Drop a plumb line down from the ceiling to the position of the fireplace exit flue. Mark the center point where the vent will penetrate the ceiling. Drill a small locating hole at this point. Drop a plumb line from the inside of the roof to the locating hole in the ceiling. Mark the center point where the vent will penetrate the roof. Drill a small locating hole at this point.

Installation Continued Install a sediment trap between incoming gas line and gas control box (see Figure 23). The sediment trap should extend down a minimum of 3" (7.62 cm) beyond center of pipe. When routing gas line through conduit sleeve, make sure to repack insulation to fill gaps between gas line and conduit sleeve. Compounds used on threaded joints of gas piping shall be resistant to the action of propane or natural gas. Compounds should be applied lightly to ensure excess sealant does not enter gas line. Complete your gas line installation by connecting incoming gas line to flexible gas line. Secure tightly with a wrench but do not over-tighten. WARNING: All gas piping and connections must be tested for leaks after the installation is completed. Never use an open flame to check for a leak. After ensuring that the gas valve is open apply commercial leak detection fluid to all gas joints. Bubbles forming show a leak. Correct all leaks at once. Do not operate any appliance if a leak is detected. Gas Routing (Right Side Not Shown) Incoming 1/2" Gas Line Permitted By Local Codes Sediment Trap (Not Supplied) 3" Min.

Installation Continued Lava Rock and Ember Material 1. For all models, place lava rock along sides and front of firebox bottom in areas that are visible. It is not necessary to use all lava rock provided. NOTICE: Do not put lava rock on or under burner. Placing lava rock on burner could cause performance problems. 2. Pull ember material apart into pieces no larger than a dime. Place loosely and directly onto exposed section of front burner and along space between burner and grate prongs. These will create glowing ember appearance as flame touches ember material. Do not block air slots by using too much ember material in one area. It is not necessary to use all ember material provided. 3. When lava rock and ember material are in place, close and latch glass door and secure louvers in place. Face Extension for model CD32M-B Only Model CD32M-B comes equipped with a front face extension. The front face extension would add 3 1 /2" to the width and 3/4" to the height of the fireplace face.

Operating Fireplace operation guidelines When used for the first time, the fireplace may emit a slight odor for about 16 to 24 hours. This is normal and is due to the curing of the logs and the burn-in of internal paint and lubricant used in the manufacturing process. Keep compartments, logs, burners and area surrounding logs clean by vacuuming and brushing at least twice a year or as necessary. Turn off gas and remote switch before servicing appliance. Any safety screen or guard removed for servicing the fireplace must be replaced prior to operation. Have a qualified agency periodically inspect vent system at the start of each heating season for any obstruction which will hinder its normal operation. Never obstruct the flow of combustion and ventilation air. Keep the front of the fireplace clear of all obstacles and materials.
